As a man reaches climax whilst in the "doggie style" position, the man pulls out and spits on their partner's back, fooling them into thinking that he has ejaculated, however, when their partner turns around, the man lets loose his baby yoghurt in his partner's face.

a houdini can also refer to a sex act where a male, who is fucking a chick doggy style in front of a first floor window, quickly pulls out, and his friend jumps in to continue banging her. the first man then proceeds to run naked and dance in front of his bitch outside the window. magic, eh?

nonetheless, the more accepted defineition is the genuine spit and skeet technique.

Named for the infamous magician, the houdini is a sexual act in which a male engages his partner from behind and prior to ejaculating he pulls his penis out and spits on his partners back to simulate ejaculate. When his partner turns around he then ejaculates into his partner's face.

When a man has sex with a woman so that he is behind her and she is facing a window. The man has his friend hide in the in the room and during the middle of the act the man pulls out and his friend takes his place so that the woman does not notice. The man then runs outside and waves to the woman from outside of the window.

Me and Jim pulled the houdini perfectly last night. The girl had no idea how I escaped.
